i have been having an issue with my 85 500sel lately. when the car is
under load with 2 people while driving, i feel a nasty shake and it
makes a hum. also around 60mph i feel a vibration under the driver's
took the car to the dealer yesterday and had them look into the
driveshaft. the both flex disks and the center support bearing
checked out fine. final diagnosis was that i need to replace the rear
subframe bushings and rear upper control arms. they say the rear end
is loose. come to think of it, when i go over bumps, i can hear
My questions: why the control arms? do they bend after 200000mi?
isn't it the bushings? how manay are there?
thank you in advance
